Abstract
A high voltage direct current transmission includes a rectifier station and an inverter station each connected to an AC network and connected together by a DC line. In order to limit over-voltages on the line and in the rectifier station on starting the station towards an open line, this station is provided with an arrangement which senses the voltage and the current of the station and is connected by level indicators for maximum voltage and minimum current to a signal emitter which reduces the direct voltage of the station in response to a direct voltage above a certain level and a direct current below a certain level.
